PAPERI-CLIP.

SPECIFICATION forming part of Letters Patent No. 749,429, dated January12, 1904.

Application filed September 24, 1901. Serial No. 76,360. (No model.)

To all whom it may concern:

Be it known that I, GEORGE BROWN DUSIN- BERRE, a citizen of the UnitedStates, residing at Edgewood Park, in the county of Allegheny and Stateof Pennsylvania, have invented a new and useful Improvement inPaper-Clips,

of which the following is a specification. My invention relates'todevices for clamping together sheets of paper; and it has for its objectto provide a device of this character which shall be simple andinexpensive in construction, which shall be adapted for securely holdingtogether with equal facility either a small or a large number of sheets,and which may be readily applied and detached without danger ofpermanent distortion from the original shape.

My invention is susceptible of embodiment in a variety of forms, some ofwhich are illustrated in the accompanying drawings, in

which Figure 1 is a front elevation of one form of my invention. Fig. 2is a front elevation of y a device similar to that shown in Fig. 1, butembodying a slight modification. Fig. 3 is a front elevation of a devicesimilar to Fig. 1, but having a still further modification of form. Fig.4 is a front view of another modification, and Fig. "5 is an edge viewof the device shown in Fig. 4.

Referring now particularly to Fig. 1, the clip 1 is formed of a singlepiece of wire of such composition that it may be readily bentsufficiently to perform its functions, but sufficiently resilient sothat it will return to its original condition when released fromtheforce that holds it in the deflected position. The device comprises aloop 2 at one end, which may constitute a handle for use in applying thedevice to sheets of paper and for removing it therefrom. The ends 3 and4 of the loop 2 project away from each other at a considerable angle tothe points 5 and thence toward each other, so that their ends overlap,and then backward upon themselves to form double arms 6 7 and 8 9.Either side of the device may be regarded as the front; but forconvenience of description and definition the side presented to view inthe drawings will be designated as the front and the opposite side asthe rear? It will be observed that the front arm 6 7 constitutes acontinuation of the rear loop end 3, and consequently that the rear arm8 9 constitutes a continuation of the front loop end 4, from which itfollows that the pressure exerted by the sheets to force the arms 6 7and 8 9 away from each other is resisted by the loop and its ends andthat consequently with this arrangement of parts the arms 6 7 and 8 9grip the sheets to which they are applied firmly, whether the number besmall or large, and the restoration of the parts to their originalpositions when the clip is removed from the sheets to which it has been.

applied is insured. A further important and characteristic feature ofthis embodiment of my invention is the cooperative relation of thegripping-arms, whereby three gripping or pressure points areprovidedviz., one between the arms 6 and 9, one between the arms 7 and8, and the third between the arms 6 and 8. Inasmuch as the gripping orpressure points are symmetrically located and two of them are side byside and substantially the same distance from the loop 2, which distanceis comparatively short, the gripping action is so exerted as to holdtogether either a small or a large number of sheets without substantialdifierence of efliciency.

In the device shown in Fig. 2 the several parts are the same in form andrelative location as in the device shown in Fig. 1 except that free ends10 and 11 of the arms 6 7 and 8 9 are bent inwardly slightly toward theplane of the clip, so that when the clip is applied to a plurality ofsuperimposed sheets the bent-in ends grip the outer sheets and serve tolock the device in position. This prevents the accidental slipping offor removal of the clip, but does not prevent its ready removal, providedthe arms 7 and 9 are grasped and sprung apart.

In the device shown in Fig. 3 the parts are exactly the same inconstruction and arrangement as in the device shown in Fig. 1, exceptthat the loop 2? is flattened and elongated, so

as to project a materially less distance from the edges of the sheets towhich the device is applied. The other parts, being designated by thesame reference-numerals as in the preceding figures, need not be againdescribed.

The device shown in Figs. A and 5 has a loop 2 and loop ends 3 and 4:,that are substantially the same as the corresponding parts shown inFig. 1. The arms 6 and 8, however, terminate with their free ends at theextreme limit of the device instead of being extended to formsupplemental arms 7 and 9 opposite the loop 2. The free ends 12 and 13are bent slightly outward from the plane of the clip in order tofacilitate the application and removal of the device from the sheetsheld by it. This last feature is not essential, but it facilitates theuse of the device. It will be noted that in this case, as in Fig. 1, thefront arm 6 is a continuation of the rear loop end 3, and consequentlythat the gripping action of the clip, which has been described inconnection with the device shown in Fig. 1, obtains also in this form.

Other variations in the form of the device may obviously be made, and Itherefore do not desire or intend to limit my invention to exactly whatis shown in the drawings.

I claim as my invention- 1. A paper-clip formed of a single piece ofWire and comprising a loop and gripping-arms that first diverge from theloop and then converge toward and across each other in such manner thatthe front arm is a continuation of the rear terminal of the loop.

2. A paper-clip comprising a loop and two angular gripping-arms thatfirst diverge from the loop and then converge toward and across eachother neartheir outer ends so that the front arm is an extension of .therear terminal of the loop and the arms exert a gripping actionsubstantially at right angles to the plane of the clip.

3. A wire paper-clip comprising a loop and two arms that cross eachother and are bent backward upon themselves to form supplemental armsthat cross the main arms, thus providing three gripping-points, thefront arm being a continuation of the rear terminal of the loop.

4:. A wire paper-clip comprising a loop and two projecting arms thatcross each other and are bent backward upon themselves to formsupplemental arms which cross the main arms, thus providing threegripping-points.

5. A wire paper-clip comprising a loop and two projecting arms thatcross each other and are bent backward upon themselves to formsupplemental arms which cross the main arms, thus providing threegripping-points, the free ends of the supplemental arms being bentinward toward each other for locking the clip in position.

6. A wire paper-clip having two grippingarms severally embodying singlereturn-bends and crossing each other at both sides of said bends therebyproviding three grippingpoints. I.

7. A paper-clip formed of a single piece of wire and comprising a loopand gripping-arms that first diverge from the loop, then converge towardand across each other and are then bent back-ward across each othertoward the loop, thus providing three gripping-points.

In testimony whereof I have hereunto subscribed my name this 18th day ofSeptember, 1901.
